i To all whom concerni I Be it known that we, Trroiiras L. Ryan andOVERTOX SAcKs'niDnmfJn, cltizens of the United States,-res1dmg atMuncie, 1n the county of Delaware and State of Indiana,

have invented certai-njnew' and useful Improvenients in Shade-Holders,of Which the followingzisj a specification.

There being aslightclearance space 3'between the innersurfa'ce of the cap, and. the outersurface- 0f -the rim edgeof' the' 1 glass, it is practicable to adjusttheshade in any direction necessary that the bottom a lineof.'tl1esl1ade mayjbeperfectlyat aright angleto thel center line of theholder, and therefore'of the fixture coluninl.

This adjustment feature is essential for the reason that shades made ofglass are not perfect in contour. That is to say,

although the glass may be-castin perfectly I machined molds, the glassshade itself, after being cooled and annealed, is not uniformly iperfect"; a large proportionof glass shades bc-nig .out of round. 5 I I7 To meet-this physical defect in the glass "Sl1aClS ,-'tl16 degree of;curvature, horizorr tally,'of the cross arms, is slightly greater thanifof a degreeiof curvature struck from a point centralof-these cross arms{The.

same thing;- is true of the degree of a curvature of the vertical curveD This of-the surface "of the cross ar1n., 'It is ap-:

Iparent that by this arrangementthc under 2 -[1, 3s3,7ee

side of the shade is engaged bythe end p01- tion and by the horizontalportionof the cross arms intermediate the top and bottom edges. WViththe construction and combination with the side arms A and A, of thecross armsD and D as shown and described, there may be retainedpracticably by this holder device, glass shades of the standardcommercial type; and the shades will beretained securely and accurately,even though theW-int-ennal contour of :the shade may be,

as above referred to, technically imperfect.

1 Moreover, the shade, so supported cannot become loose or Wabbly andthe lamp as an entirety may be shifted and moved about without risk ofdamage'to the shade.

It will be understood that the above detailed description as to thecurvature horizontally and vertically ofthe cross arms, is

not intended as a limitation of the scope of this invention; it beingapparentthat cross arms of angular formation would perform the samefunction, though not quite so desirably, asthat performed by the crossarms formed as above described. Also it might be desirable, ifnecessary, to construct the precisely register with fihecontour ,of thecross arms of a predetermined contour to under side of the metal orglass shade to be used. Another advantageof the invention is that thesecuring of the holder :to the lampbase isvery simple; the bottom plateBibeing seated on the faced top of the "base column 1; the electric,socket 4 is screwed down on the threaded nipple 5 that is passed.through the holewB and the holder'frame is thuswtightened securely ataccurately alined position.

What we claimias ourunventron, and desire to secure by Letters Patent1s:

. 1. In a shade holder, an integral harp shaped member having the archedupper ends of the sides thereof formed at their juncture with anintegral stem, a cross arm on eachof said arched parts extending onopposite sides thereof and disposed at ing member secured tothe' stem. I

' spacedpoints below the stem, and a retaing Y 2. a shade holder,aharp-shaped, memher, a cross arm on each of the arched upper ends of thesides of the member located at points spaced below the top of themember, whereby the :Weight of the shade is borne directly by the archedupper ends ,of

the member, and means to secure the shade tofthemember. 7 V

38. In a'shade holder, an integral harp shaped member; having the archedupper ends of the sides thereof formed at their uncture with an integralstem, a cross arm on each of said arched parts extending on oppositesides thereof anddisposed at spaced points below the stem, and saidcross arms having .dished outer faces and being relatirely thick andwide and of, approximate rectangular formation, and a retaining mem--ber secured to the stem.

4:. In a shade holder, a harp-shaped memher, a shade bearing elementon-each of the arched upper endsof thesides of the memand aretainingelement for "the shade borne by the frame. i. i 7

In testimony whereof We aflix our signatunes. v
